Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a load-bearing structure for a villa elevator. Background Technology

[0002] As residents' living standards improve, the demand for villa elevators continues to grow. The machine room beam, as a core load-bearing component, directly affects the elevator's safety and lifespan. Currently, the industry mainstream adopts a "wall-embedded" method for fixing the machine room beam: first, the beam dimensions are measured and marked at a predetermined position on the wall; then, grooves are cut into the wall using equipment to create recesses; finally, the beam is embedded and fixed through grouting, welding, and other methods to achieve load-bearing support. However, this method has obvious drawbacks: Low construction efficiency: Villa walls are made of various materials (brick and concrete, reinforced concrete, etc.), resulting in significant differences in the difficulty of grooving. Furthermore, dimensional deviations require secondary repairs, which prolongs the assembly cycle. Damaging the wall structure: It can easily damage the wall reinforcement and insulation / waterproofing layer. Improper operation may damage the load-bearing performance, create hidden dangers of cracking and water seepage, and increase maintenance costs. Poor working environment: Trenching generates a large amount of dust, noise and construction waste, which pollutes the environment and endangers the health of construction workers, which does not conform to the concept of green and safe construction. In summary, the existing "wall-cutting and embedding" method is insufficient in terms of efficiency, wall protection, and environmental adaptability. There is an urgent need for a server room beam fixing solution that does not require on-site grooving, ensures the integrity of the wall, and is highly efficient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a load-bearing structure for villa stairs that does not require slotting for installation.

[0004] A villa staircase load-bearing structure designed for this purpose includes a front guide rail assembly, a rear guide rail assembly, a front crossbeam assembly, a rear crossbeam assembly, and a frame for fixing the main unit. The front guide rail group and the rear guide rail group are arranged at a distance from each other. The front crossbeam assembly is fixedly connected to the front guide rail assembly; The rear crossbeam assembly is fixedly connected to the rear guide rail assembly; One end of the frame is fixedly connected to the front crossbeam assembly, and the other end is fixedly connected to the rear crossbeam assembly.

[0005] Preferably, the front guide rail assembly includes two front guide rails spaced apart on the left and right sides; The front crossbeam assembly includes front crossbeam members that are spaced apart and connected to each other; the front crossbeam members are fixedly connected to the left and right front guide rails.

[0006] Preferably, the front guide rail extends at least partially between the front and rear crossbeams and is fixedly connected to the front crossbeams.

[0007] Preferably, the front crossbeam is made of channel steel.

[0008] Preferably, the rear crossbeam assembly includes two rear guide rails spaced apart on the left and right sides; The rear crossbeam assembly includes two rear crossbeams spaced apart front to back and two connecting members spaced apart left to right; the connecting members are fixedly connected to the two rear crossbeams. The rear guide rail is fixedly connected to the connector or the rear crossbeam.

[0009] Preferably, a vertically continuous connecting space is formed between the two rear crossbeams, and the rear guide rail passes through the connecting space.

[0010] Preferably, the rear guide rail is fixedly connected to the connector.

[0011] Preferably, it also includes several fasteners, which are arranged in a left-right direction; the rear crossbeam has several welding notches arranged in a left-right direction.

[0012] Preferably, the rear crossbeam is made of sheet metal.

[0013] Preferably, the frame includes main beams spaced apart on the left and right sides; the main beams extend forward and backward. A connecting plate is fixedly connected between the left and right main beams; A mounting plate is fixedly connected to the bottom surface of the main beam near the front crossbeam assembly, and the mounting plate is fixedly connected to the main beam and the front crossbeam assembly.

[0014] Compared with the prior art, this utility model effectively solves many defects of the existing "wall-embedded" fixing method for computer room beams, and has the following core beneficial effects: Effectively avoids on-site grooving and protects the integrity of the wall structure: This structure eliminates the need to cut grooves in the villa walls. It directly connects the front and rear guide rail assemblies with the front and rear crossbeam assemblies, and combines them with the frame to achieve the main unit's load-bearing support. This fundamentally avoids damage to the wall reinforcement, insulation layer, and waterproof layer, eliminating potential hazards such as wall cracking and water seepage. At the same time, there is no need to worry about damaging the building's load-bearing structure, reducing the villa's later maintenance costs. It is suitable for villas with various wall materials (such as brick-concrete and lightweight walls) and structures (such as curved walls). Improve construction efficiency and achieve standardized assembly: The components adopt a direct fixed connection method, eliminating the need for complex processes such as on-site measurement and grooving, and secondary repairs, thus simplifying the construction process; In addition, the front guide rail assembly, rear guide rail assembly, crossbeam assembly and frame can be prefabricated, and on-site assembly only needs to be carried out according to the standard process, which significantly shortens the on-site assembly cycle. Optimize the working environment and ensure construction safety and environmental protection: Since there is no on-site trenching, dust, high-frequency noise and construction waste can be eliminated, avoiding pollution to the interior environment and surrounding areas of the villa, which is especially suitable for villas that have been partially renovated; at the same time, it reduces the risk of construction workers being exposed to dust and noise, which is in line with the concept of green construction and safe construction.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] See Figures 1-5 A load-bearing structure for a villa staircase includes a front guide rail assembly 10, a rear guide rail assembly 20, a front crossbeam assembly 30, a rear crossbeam assembly 40, and a frame 60 for fixing a main unit 50; the front guide rail assembly 10 and the rear guide rail assembly 20 are spaced apart front to back; the front crossbeam assembly 30 is fixedly connected to the front guide rail assembly 10; the rear crossbeam assembly 40 is fixedly connected to the rear guide rail assembly 20; one end of the frame 60 is fixedly connected to the front crossbeam assembly 30, and the other end is fixedly connected to the rear crossbeam assembly 40.

[0018] The load-bearing structure of this villa staircase adopts an assembly logic of "step-by-step positioning and sequential connection". The core revolves around the basic positioning of the front guide rail assembly 10 and the rear guide rail assembly 20, and the assembly of the crossbeam assembly, frame and main unit is completed step by step. The specific process is as follows: First, the basic guide rail assembly is positioned and fixed. Based on the shaft design dimensions and elevator installation parameters, the front guide rail assembly 10 and the rear guide rail assembly 20 are fixed to the preset positions on the inner wall of the shaft according to the "front-to-back spacing" requirement. Positioning components (such as guide rail brackets and expansion bolts) are used to ensure that the verticality, parallelism, and spacing of the two guide rail assemblies meet the installation standards, forming the basic support frame of the load-bearing structure and providing a precise positioning benchmark for subsequent component assembly. Secondly, the corresponding connection between the crossbeam assembly and the guide rail assembly is achieved. After the front guide rail assembly 10 and the rear guide rail assembly 20 are fixed and secure, the front crossbeam assembly 30 is installed to the preset connection position of the front guide rail assembly 10, and the two are rigidly fixed by means of bolt tightening, welding, etc. At the same time, the rear crossbeam assembly 40 is connected to the rear guide rail assembly 20 to ensure that the front crossbeam assembly 30 and the rear crossbeam assembly 40 form a stable integrated structure with the two guide rail assemblies respectively. At this time, the crossbeam assembly acts as an intermediate supporting component, completing the connection and transition between the guide rail assembly and the subsequent frame. Finally, the frame and main unit are assembled. First, one end of the frame 60 is aligned and fixed with the preset connection point of the front crossbeam assembly 30, and the other end is fastened to the corresponding connection point of the rear crossbeam assembly 40, so that the frame 60 spans between the front and rear crossbeam assemblies, forming the installation carrier of the main unit 50. After the frame 60 is assembled and stabilized, the main unit 50 is hoisted to the preset installation position of the frame 60, and the main unit 50 is rigidly connected to the frame 60 by positioning pins, fastening bolts and other components, thus completing the assembly of the entire load-bearing structure. The main unit 50 transmits the load to the guide rail assembly through the frame 60 and the crossbeam assembly, and then the guide rail assembly evenly distributes the load to the shaft, realizing the stable load-bearing support of the main unit.

[0019] See Figures 1 to 5 The front guide rail assembly 10 includes two front guide rails 110 spaced apart on the left and right; the front crossbeam assembly 30 includes front crossbeam members 310 spaced apart front and rear and connected to each other; the front crossbeam members 310 are fixedly connected to the two front guide rails 110 on the left and right. In this embodiment, the front guide rail assembly 10: through the two front guide rails 110 spaced apart on the left and right, forms a symmetrical and stable vertical support reference in the shaft, which not only provides precise left and right positioning points for the front crossbeam assembly 30, ensuring that its installation position is centered and compliant, but also evenly distributes the load transmitted subsequently, avoiding unilateral force concentration; at the same time, the spacing design of the two guide rails is also adapted to the width of the shaft, providing a reliable vertical bearing foundation for the overall load-bearing structure. Front crossbeam assembly 30: The front crossbeam 310, which is spaced apart and interconnected, is fixedly connected to the left and right front guide rails 110. On the one hand, the "front and rear spaced" structure enhances its own resistance to deformation and improves the lateral load-bearing stability; on the other hand, it forms a connection platform that adapts to the frame 60, realizing the rigid connection between one end of the frame and the front guide rail assembly, ensuring that the main load can be smoothly transferred to the front guide rail assembly and then distributed to the shaft.

[0020] See Figure 1 and Figure 2 The front guide rail 110 extends at least partially between the front and rear front crossbeams 310 and is fixedly connected to the front crossbeams 310. On the one hand, this allows the front guide rail and the front crossbeam assembly to form an "interlocking" rigid connection, significantly improving the tightness and firmness of the connection and preventing loosening of the connection due to load. On the other hand, the main load borne by the front crossbeam assembly can be more evenly transferred to the front guide rail assembly through the interlocking guide rail section. At the same time, the bidirectional limiting of the front and rear crossbeams reduces the vertical or lateral displacement deformation of the front guide rail, further strengthening the stability of the support structure composed of the front guide rail assembly and the front crossbeam assembly.

[0021] In this invention, the front crossbeam 310 is made of channel steel. Different specifications of channel steel are selected from those available on the market to meet various installation requirements.

[0022] See Figure 3 The rear crossbeam assembly 40 includes two rear guide rails 210 spaced apart horizontally; the rear crossbeam assembly 40 includes two rear crossbeam members 410 spaced apart front to back and two connecting members 420 spaced apart horizontally; the connecting members 420 are fixedly connected to the two rear crossbeam members 410; the rear guide rails 210 are fixedly connected to the connecting members 420 or the rear crossbeam members 410. In this embodiment, the rear crossbeam assembly 40: the two rear crossbeam members 410 spaced apart front to back, together with the connecting members 420 spaced apart horizontally, form a frame structure, which enhances its torsional resistance through the "front-to-back spacing" and achieves a stable connection in the left and right directions with the help of the connecting members; at the same time, it provides multiple fixing interfaces (connecting members 420 or rear crossbeam members 410) for the rear guide rails 210 to ensure accurate installation of the rear guide rails. The rear guide rail 210 and the component: The left and right spaced rear guide rails 210 are fixedly connected to the rear crossbeam component 40. On the one hand, they bear the host load transmitted by the component and distribute it evenly to the shaft. On the other hand, they form a "vertical-lateral" collaborative support with the component, restricting the displacement and deformation of the rear crossbeam component. Together, they provide a stable force-bearing foundation for the other end of the frame 60 and ensure the balance of the overall load-bearing structure.

[0023] See Figure 3 A vertically connected space 400 is formed between the two rear crossbeams 410, and the rear guide rail 210 passes through the connected space 400. The vertically connected space design accommodates the vertical extension requirements of the rear guide rail 210, avoiding the additional occupation of redundant vertical space in the shaft due to component connection. At the same time, it eliminates the need for separate slots or additional support structures on the inner wall of the shaft, further reducing unnecessary space consumption and ultimately achieving efficient utilization of the shaft space. It is especially suitable for scenarios where the size of villa stairwell shafts is relatively compact, improving the utilization rate of shaft space.

[0024] See Figure 3The rear guide rail 210 is fixedly connected to the connector 420, and the two can be connected by existing connection structures such as welding or bolting.

[0025] See Figure 4 It also includes several fasteners 80 arranged in a left-right direction; the rear crossbeam 410 has several welding notches 411 arranged in a left-right direction; the fasteners 80 are at least partially inserted into the welding notches 411 and welded to the rear crossbeam 410; the frame 60 is fixedly connected to the fasteners 80. Through the "partial insertion + welding" method, on the one hand, precise positioning and stable connection between the fasteners and the rear crossbeam are achieved, avoiding the need for additional connecting parts that would occupy shaft space; on the other hand, the left-right arrangement design can flexibly adapt to the width of the frame 60, without adjusting the overall structure of the rear crossbeam, by selecting the corresponding fasteners to connect to the frame, ensuring connection strength and further optimizing the layout of internal components in the shaft, reducing space waste, and adapting to the compact shaft scenario of villa stairs.

[0026] In this invention, the rear crossbeam 410 is a metal plate. The design of the metal plate is mainly based on the fact that the rear crossbeam assembly 40 is located on the rear side of the shaft, where there is not much space to accommodate the rear crossbeam 410. Therefore, the rear crossbeam 410 made of metal plate is combined with the connector 420, and the rear guide rail 210 is inserted into the connecting space 400, which makes reasonable use of space and ensures the overall load-bearing capacity.

[0027] In this utility model, the frame 60 includes main beams 610 spaced apart on the left and right sides; the main beams 610 extend in the front and rear direction; a connecting plate 620 is fixedly connected between the two main beams 610 on the left and right sides; a mounting plate 70 is fixedly connected to the bottom surface of the main beams 610 near the front crossbeam assembly 30, and the mounting plate 70 is fixedly connected to the main beams 610 and the front crossbeam assembly 30.
